582-04 - HRSG - Auxiliary Equipment and Systems
Learning objectives
- Recall the purpose of the following systems: supplementary firing, bleed air, deaerator, attemperator, sampling, dosing, selective catalytic reduction (SCR), CO catalyst, and nitrogen
- Identify the general location of the following systems: supplementary firing, deaerator, selective catalytic reduction (SCR), and CO catalyst
- Relate the operating conditions in which supplementary firing would be impactful
- Describe the mechanism by which deaerators fulfill their purpose
- List some qualities for which analyses are frequently performed in the steam/water cycle
- State why SCR systems and CO catalyst systems have been put in place
- Relate what operating conditions a nitrogen system would be used in
Course overview
The main components of a heat recovery steam generator (HRSG) were discussed in the previous lesson. Many other systems also contribute to safe, efficient, and environmentally safe HRSG operation. The HRSG - Auxiliary Equipment and Systems training course identifies auxiliary system found in an HRSG unit. It also discusses their purpose and how they benefit the unit. This course is part of the Combined Cycle Power Plant Operations series.
